GRAIN-CAR DOOR.

To all whom it may concern:

Be .it known that 1, JAMES ELMER FAU- cn'r'r, a citizen of the UnitedStates, and a resident of Kenmare, in the county of WVard and State ofNorth Dakota, have made certain new and useful Improvements in Grain-OarDoors, of which the following is a specification.

My invention relates to improvements in grain car doors, and it consistsin the constructions, combinations and arrangements herein described andclaimed.

The main object of my invention is to provide a door for a grain carwhich may be easily opened after the car has been filled with grain,notwithstanding the pressure exerted by the grain itself. In fact, thepressure of the grain upon the door facilitates the opening of thelatter as will appear from the following specification.

A further object of my invention is to provide a door of great strengthin comparison with its weight so that it can resist any ordinarypressure applied thereto.

A further object of my invention is to provide an improved lockingdevice by which the door is absolutely locked against accidental openingalthough it can be readily opened when desirable.

Other objects and advantages will appear in the following specificationand the novel features of the device will be particularly pointed out inthe appended claims.

My invention is illustrated in the accompanying drawings, in which-Figure 1 is a side view of a portion of a car equipped with my improveddoor. Fig. 2 is an enlarged section along the line 22 of Fig. 1. Fig. 2is a similar view showing the stop moved to permit the door to swingoutwardly. Fig. 3 is a fragmentary view of the lower part of the doorshowing the flanged bottom for preventing an upward movement. Fig. i isa perspective view of the locking mechanism. Fig. 5 is a view showingthe detailed construction of the stop and slide, and Fig. 6 is a sectionof a box car showing the manner of elevating the door when the latter isnot in use.

In carrying out my invention I provide vertical grooves A in'the doorframes B of the car O on the opposite sides of the door openinWithin'the grooves A is disposed a slide D of the form most clearlyshown in Fig. 5. This slide consists preferably of an Specification ofLetters Patent.

angle iron having the flanges (Z secured to one side and extending in adirection parallel to the other side, the stop member cl and theconnecting top portion d. The slide D is disposed in the slot A in themanner clearly shown in Figs. 2 and 2.

On the outer edges of the door frame B are secured the plates E havingthe curved flange portion 6. The opposite side 0 of the plate E extendspartly over the slot A but terminates about mid-way so as to leave anopening 6 The stop or main locking member F is best shown in Fig. 5. Itconsists of a plate of approximately L-shape in cross-section, havingthe longer arm f inclined at an angle to the short arm The latter isprovided with the recesses f which are arranged to receive the lugs (Zon the slide D when the parts are in registration. The shorter arm ofthe stop F is disposed within the slot A while the end of the longer armf is arranged to be loosely held by the flange 6 of the plate E.

In the top of the slot A is a hinged member Gr whose lower end 9 isarranged to engage the stop d as clearly shown in Fig. -Il. On the innerside of the door frame is a plate H having an outwardly turned flange72..

The door K itself preferably consists of one piece and may be made ofany suitable material. The door illustrated in Fig. 3 is a metal doorand has an integral flange 70 on either side, and a bottom flange le Thedoor K is suspended by means of the chains or other suitable flexiblemembers M. The point of attachment of the chains M and the door K isapproximately one-half of the distance from the door sill to the lintelas shown in the figure.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

Figs. 2 and a show the mechanism in position for receiving the door. Inthis position the slide D has been raised in which position it is heldby the engagement of the lug cl by the pivoted member Gr. It is thiselevated position of the slide 1) that brings the flanges (Z intoregistration with the openings f in the stop F and permits the latter tobe pushed inwardly as clearly shown in Fig. 2. The flanges 7c of thedoor K are now brought between the flanges h of the side plates H andthe door frame B as Patented Mar. 15, 1910.

shown in Fig. 2-. The pivoted member G is now swung outwardly therebyallowing the slide D to drop when the flanges (Z will engage the sides fof the stop F and draws the latter out 'ardly as shown in Fig. 2. Thislocks the door K securely in position. In order to prevent the door fromworking upward, I provide the bottom flanges 70 see Fig. 3, which enterthe spaces It at the bottoms of the plates 72. thereby preventing anyupward movement until the door is swung clear of the parts. lVhen theslides D are lowered the pivoted member Gr may be swung in above the lug(Z thereby locking the slide in position and absolutely preventing itsaccidental upward movement, and the release of the stops F. hen the cararrives at its destination the pivoted member G is swung outwardly, theslides D raised and suspended in the manner already described and thestops F are then driven in toward the door frame by means of sledges orother suitable tools. As soon as the stops clear the edges of the doorthe weight of the grain forces the latter outward. It will be seen thatthe emptying of the car may be accomplished very quickly by merelyraising the slides and forcing back the stops.

In Fig. 6 I have shown how the swinging door may be elevated out of theway when not in use. From this figure it will be seen that the doorafter being released may be passed through the door opening to the innerside of the car, turned upwardly against the supporting chains, raisedto the roof of the car and there kept suspended by means of the hooksIt. This provides a convenient means of holding the door when not inuse, and permits ready access to the latter when necessary.

I claim:

1. The combination with a. vertically slotted door frame of a car, of apair of flanged plates secured to the door frame on opposite sides ofthe doorway, a flanged door suspended in front of said doorway, andarranged to engage said flanged plates on one side thereof, a movablestop member secured to the door frame on the outer side of the door andhaving an arm arranged to project within the vertical slot, said movablestop member extending the full height of the door, and means disposedwithin said slot for normally keeping the movable member in the path ofthe door, said means being adapted to move so as to permit the inwardmovement of the stop members, out of the path of the door.

2. The combination with a vertically slotted door frame of a car, of apair of flanged plates secured to the door frame on opposite sides ofthe doorway, a flanged door suspended in front of said doorway, andarranged to engage said flanged plates on one side thereof, a movablestop member loosely secured to the door frame on the outer side of thedoor and having an arm arranged to project within the vertical slot, themovable stop member extending the full height of the door, and a slidedisposed in the vertical slot having cam members normally in engagementwith said arm for holding said stop member in the path of the door, andadapted to be moved vertically to free the arm, and permit its inwardmovement, thereby allowing the door to swing outwardly.

8. The eon'ibination with the slotted door frame of a car, of a flangeddoor suspended in the door way, a flanged plate secured on each side ofsaid door frame and adapted to engage the flanged portions of the doorto prevent inward movement of the latter, L-shaped slotted stop membersmovably secured to said door frame on each side thereof and arranged toproject into said slots and slide disposed in said slots having lugsarranged to engage said stop members for forcing the latter outwardly tocover the edges of the suspended door thereby preventing it fromswinging outwardly, said slides being adapted to be moved vertically tobring said lugs into registration with the openings in said stop membersto permit the latter to be moved inwardly to release the door.
